JOHN DUFFY, OF CHICAGO, ILLINOIS.

FUEL-MIXER.

To all whom'z't may concern:

Be it known that I, JOHN DUFFY, a citizen of the United States, ,and aresident of the city of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Fuel-Mixers, ofwhich the following is a specification.

My invention relates to improvements in fuel mixers for use inconjunction with internal combustion engines, and adapted to supply amixture of air and steam to the explosive charge, the object of theinvention being to provide a simple and efficient device of thischaracter which may be readily applied to any of the usual forms of suchengines, and which is capable of uniform operation.

The invention consists in the combinations and arrangement of partshereinafter described and claimed.

The invention will be best understood by reference `to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is an end View of a fuel mixer embodying the invention,

F ig. 2, a view of the opposite end thereof,

Fig. 3, a top plan view corresponding with Fig. 2,

Fig. 4, a. vertical section of a valve corresponding with Fig. 1, and

Fig. 5, a section taken on line 5 5 of Fig. 2.

The preferred form of construction 'as illustrated in the drawingscomprises a cylindrical casing 6 havinga threaded stud 7 at one endthereof,-and by means of which the device may be readily mounted on theexhaust manifold of an ordinary internal combustion or'explosive engine.The casing 6 is provided at one side with a horizontally extendingthreaded nipple 8, adapted to rcceive the end of a pipe 5). which inturn is connected with the intake pipe of the engine. At its oppositeside casing 6 is provided with another threaded nipple l() leading.horizontally thereinto and connected with a pipe 11, which -leads to thewater jacket of the engine for supplying water to the device. Thepassage of nipple 10 leads to a port 12 leading into the interior ofcasing 6 and controlled by a needle valve 13,

as shown. A'plurality of air inlet openings or ports 14 are provided inthe closed end of casing 6, a hollow rotary valve 15, operating incasing 6, being inserted therein through the open end thereof. Valve 15is rotatably mounted on a central stem or stud 16 `projecting from theclosed end of casing-""6, through the open end thereof, and said valveis held to its seat by means of a compression spring 17, as shown. Valve15 is provided with an outlet port 18 arranged to register with thenipple 8 to permit the passage of air and steam to the engine intakethrough pipe 9, and a peripheral groove 19 is provided in valve 15 toregister with port 12, and leading to a port 20 to admit water from pipe11 to the interior of valve 15. The inner end of valve 15 is closed by aplug 21 having ports 22 therein, adaptedto register with "the ports 14,as shown, the outer end of valve 15 being closed by a plate 23 formedintegrally therewith. Plate 23 is provided with two substantiallydiametrically disposed operating arms 24 formed integrally therewith,and two substant-ially diametrically disposed supporting arms 25 areformed integrally with casing 6- and provided .with threaded sockets 26at their outer ends. The sockets 26 are arranged to receive the outercasing/or flexible pipe 27 of a Bowden wire, the interior wire 28thereof being arranged to be connected with the corresponding arm 24which is perforated for the purpose.

vBy this arrangement it will be' observed that the Bowden wire may bereadily connected with either of the arms 24, and that operation of saidBowden wire by applying tension thereto, will serve to open the valve 15to permit passage of air and steam to the engine intake. and thatcompression applied to the Bowden wire will close vsaid valve. Thus thedevice may be applied to any ordinar)7 internal combustion or explosiveengine and the Bowden wire operating connecsuitable quantity of airbefore being sup. vplied to the explosive mixture. The plurality of airinletports 14l22 serve to supply ample air to the device without noise,and the, valve is so designed and constructed that the more the port l2is opened to admit more water, the more ports 14 are opened to admitmore air and thus regulate this supply of air in proportion to theamount of water admitted. The specific form and arrangement of parts isa simple and emcient one for the purpose.

While l have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modilication without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what l claim as new and desire to secureby Letters Patent is:

1. A device of the class described com prising a casing; a rotary valvemember in said casing means for supplying water to said casing andconducting the same away, said means being controlled by said valve;substantially diametrically projecting operating arms on said valve;substantially diametrically disposed sockets on said casing cooperatingwith said arms; and an operating connection for said arms arranged to bemounted in eitlier of said sockets and operatively connected with eitherAof said operating arms, substantially as described.

2. A device of the class described comprising a hollow cylindricalcasing open at one end and having one or more air ports eccentricallypositioned in its other end; a 4hollow rotary valve mounted in saidcasing and closed on all sides, the inner .portion of said valve beingprovided with one or more eccentrically positioned ports adapted to bebrought into registration with the air ports in said casing; and meansfor operating said valve, substantially as'described.

3. A device of the class described c0111-, prising a casing; meansleading horizonn tally from one side of said casing for connecting saidcasing with the intake of an engine; means leadinghorizontally into theopposite side of said casing for admitting water thereto; ports in theend of said casing admitting air thereto; a rotary valve controlling thepassage from said water and air admission means to said connectingmeans; substantially diametrically disposed operating varms on saidvalve; substantially diametrically disposed sockets on said casingcooperating with said arms; and an op erating connection for said armsarranged.
